The line comes from Five Nights at Freddy's: Ultimate Custom Night, the 2018 customizable entry in Scott Cawthon's horror series where Freddy Fazbear is one of many animatronic threats. In game it plays as a taunt when Freddy senses deception, which is why fans clipped it for reactions outside the horror context. It circulates alongside the FNAF Jumpscare Scream and other UCN voice lines on soundboards, often used less for scares and more for dry, robotic suspicion in gaming edits and meme conversations.
